We offer three different types of save batteries for your games. It can be a bit confusing which one to choose.
CR1616, CR2025, & CR2032
All Game Boy games that use battery back-ups use either CR2025 or CR1616 coin cell batteries. To determine which one your game uses open them up and measure the diameter of the battery. A CR2025 coin cell battery is 20mm wide while a CR1616 coin cell battery is 16mm wide.
All Nintendo NES, Super Nintendo, Nintendo 64, Sega Genesis and Sega 32X games that use battery back-ups use CR2032 batteries and have outward prongs.
These are the batteries used only for Game Boy Advance games. They are used in Pokémon Emerald, Sapphire, Ruby, Puzzle Challenge, Yellow, and Trading Card Edition plus many other Game Boy games.
